The Three Litre House in Ludwigshafen is the result of retrofitting of a building built during the 1950s, coordinated by LUWOGE, BASF’s housing company. Thanks to accurate planning, the insulation of the roof, the walls and the ceilings with Neopor® , a plaster containing Micronal® PCM and triple glazed windows, the consumption for heating has been reduced by about 80% to 30 kWh per square metre per year, which corresponds to three litres of oil for heating or about three cubic metres of gas. |
